I bought this synthetic brush in 2015. Till this day, it's probably my most-used brush. I really like it. It cost me about 6 euros. It easily creates rich and explosive (if I may say) lather with any cream or soap, soft or hard. It has never disappointed me. It has a nice splay and a medium to strong backbone. I believe the knot is set at 24mm, the ideal size for me.

Omega brushes are classics and offer a truly great price-quality ratio.

I highly recommend it. Actually, I "have/need to" buy a few backups just in case.
